Our current emotional state drives our decisions. It can either narrow our perspective or broaden it.
For example,
When we are in a state of euphoria we overestimate our abilities and underestimate the risks, we get blind, and later we regret choices we made. For example, Peter Griffin, a character from Family Guy took an IQ test and while waiting for results, which he was sure would be fantastic, decided to hire a bulldozer to demolish his house to celebrate his genius. When the test results came back it showed that actually Peter is not a genius, he is mentally retarded. Allowing yourself to make a decision in the state of euphoria will bring dramatic consequences to the quality of your life.
When we are in a depressed state, we also have tunnel vision, we dramatize, catastrophize and make decisions that we also will regret. The most devastated example of a decision in this state is when a person committs suicide, that person is finding “a permanent solution to a temporary problem.”
Then there is a blissful state, a state of calm joy. In this state we are able to see the broadest possibilities, we stop living in black and white world, and we are moving into a world of many shades, of rainbow options. This is the state where we make the most optimal choices for ourselves. This is a state where we are not manipulated, where we are not acting out of past trauma or unhealthy cravings. It is a place where we are able to hear our heart, and our heart is able to communicate with our mind.
